Android :: Launch Intent Viewer To Display Image From Url
Jun 1, 2010
I have the url of an image. What i need to do is launch the default image viewer for images using an intent. But it doesn't work. If I do not specify the type of data, the intent launches the browser since the data is a url. It works basically (since you can see the image on the browser) but what I would like is to have the gallery display the image for me.I can also download the image into a Bitmap but I would still not know how to display the Bitmap using the gallery (if that's even possible).I tried saving the bitmap to the cache and then launch the viewer on that file but it doesn't work. Can you spot any mistakes on my code? (The Utilities class is a class i wrote.

Just wondering if its possible to use the built in image viewer to display an image sourced from a database. I'm hoping I can pass the byte[] as an extra to the ACTION_VIEW intent, but can't find any docs on it so far. Alternatively I'll have to roll my own viewer or first write the image out to a file and pass that to the intent.

I am trying to launch an email intent with an attached jpg. I did:
Intent intent4 = new Intent(Intent.ACTION_SENDTO,
Uri.fromParts("mailto", "testemail@gmail.com", null));
startActivity(intent4);
this launches the email activity.
But when I try to add DataAndType (my jpeg attachment). It fails with
android.content.ActivityNotFoundException: No Activity found to handle Intent { action=android.intent.action.SENDTO data=file:///data/data/com.mycompany.mypackage/files/temp-picture type=JPEG
Intent intent4 = new Intent(Intent.ACTION_SENDTO,
Uri.fromParts("mailto", "testemail@gmail.com", null));
intent4.setDataAndType(Uri.parse("file://"+ mTempFilePath),
Bitmap.CompressFormat.JPEG.name());
startActivity(intent4);

We can view an image with What if we have some images? How can we put the extras to let the viewer know we have /sdcard/a.jpg, /sdcard/b.jpg, /sdcard/c.jpg ? I hope to do this in a time because starting an activity is very expensive. Code...

Is there a way to launch a viewer for common file types like TXT, DOC, XLS, PDF from within an app, like Gmail does. Maybe a Google Docs api to pass the file to GD and have it open in the browser?

I do these actions on Android G1 2 times: open gallery -> view image -> Capture screen-shot -> Go back -> exist from gallery.
But captured screen-shots of 2 times are difference: the above and below background of image viewer of first time is lighter Grey, while second time is darker.
2 screen-shots:
First time: http://farm5.static.flickr.com/4064/4252991345_6ee5777bf5_o.png ,
Second time:[url]
I repeat again many time, and the "light Grey" and "dark Grey" background are alternate occurred.
Why backgrounds are not the same ? some Android optimization, cache, etc... Could you help me to find reason?

I can't find any intent which opens the camera. The closest I've found is ACTION_CAMERA_BUTTON but that breaks if the phone has no hardware button for the camera.

What is the recommended way to launch the messaging app (for sending an MMS message) via an intent? The following code works on my HTC Magic ... code..
... but it first launches the Resolver activity (com.android.internal.app.ResolverActivity), prompting the user to select the appropriate app (Email, Gmail, Messaging, Picasa). The user has to select Messaging before proceeding.
The only way I've found to bypass the resolver is to explicity set the desired component on the intent before starting the activity as follows:
intent.setClassName("com.android.mms", "com.android.mms.ui.ComposeMessageActivity");
However, I'm guessing this approach will not work on devices that have a customised UI, like the HTC Hero. Can someone confirm/deny?
I'm also struggling to find official documentation for the "address" and "sms_body" fields that can be supplied as extra data as per the above example. Is it expected that these will be supported by the default messaging app in future SDK versions and in customised UIs (like HTC's Sense UI)?

There's seemingly no way to launch the calendar app in a generic way. I've written a widget which allows you to launch the calendar. I use the following Intent:
Intent intent = new Intent(Intent.ACTION_VIEW); intent.setClassName("com.android.calendar", "com.android.calendar.LaunchActivity"); startActivity(i);
However, this doesn't work on the Hero because HTC has apparently replaced the calendar in their Sense UI. I'm looking for a "standard" way to reach the calendar. I'd like for something like this to be standardized:
Intent i = new Intent(Intent.ACTION_VIEW); i.setType("text/calendar"); startActivity(i);
Does anyone think it would be worth trying to add this to the source? It seems like there is a missing chunk of standards around calendar events and/or iCal / vCal support. Does anyone know why?

I have found various topics here and elsewhere on creating an intent for sending e-mail and that seems to be pretty straightforward. I'm looking for an intent to just launch any e-mail client the user might have.
Here is the code I've seen for sending an e-mail (posted just for reference, this doesn't serve my needs as I don't want to send a new message):code...
The code above works but isn't flexible in that a user might not be using Gmail but the other built-in e-mail application or a 3rd party e-mail app. I'm looking for an intent that would bring up the chooser in this case so the user can decide which app to launch to read e-mail.
Does anyone know how to accomplish this?

I'm trying to figure out how to launch an activity in my app from a custom URI such as myapp://myuriactivity I've read a lot about the intent and intent filters in the android references and also read several examples, but for some reason I can't get my simple test to work. Below is my manifest file, can anyone tell me what I'm doing wrong? With the below file, if I open the browser and try to navigate to http://org.test.launchtest it just says the page doesn't exist. Shouldn't this work?

Ok I have been trying to figure this out for a while. I have an application that needs to read images from a folder created by the application on the sdcard. I have no idea what the names of the files are because the user specifies the names of the files. I need to read the images from the folder and make something like the default image viewer, where you can share them delete them and things like that. Im thinking read them into a grid view first but 1) cant figure out how to dynamically read them from a folder 2) how would I implement the image options like the default viewer? If there was a way to open the default viewer on a certain folder that would help.
Anyways any input would be amazing been working on it for a while.

This is what I would like to do: => IF WiFi is enabled AND active, launch an intent (in fact it's a WebView that gets its content=>the instructions of my app on the web) => IF NOT, then I would launch another intent so that I don't show a WebView with "Web page not available ... The Web page at http://www.mywebsite.com might be temporarily down or it may have moved ..."
I tought initially to use
if(wifi.isWifiEnabled())
but that does not say if the Wifi connection is ACTIVE or not. It says only that the user has turned the switch on. The device may or may not be connected... Is this correct ?
Then I tried to use :........................

I'm launching a webbrowser via an intent, which allows my app user to login to Google Docs in a 2-legged oauth dance. This works fine, and the browser callback comes to my app with the right authentication string.
I just want to be able to kill that browser window once we are done - having it sitting there is confusing and messy.
How can I kill a browser window I started up?

Is there any way to launch an activity w/ Intents (in this case the Browser) in the background, and then bring it to the foreground using a service or activity?
I know it's possible to bring apps to the foreground by launching an intent with FLAG_ACTIVITY_BROUGHT_TO_FRONT
But is it possible to initially launch the activity in the background?
